My first attempt at mokume gane. It's just a stack of U.S. quarters, but it's fun just to run my fingers over it and look at it. It started out as $3.00 worth of quarters. Two didn't stick to the stack, but they stuck to each other. So this is $2.50 worth. I made a small press out of 1/2" steel scrap and four bolts. Pressed the stack in that and put the whole thing in the new heat treat oven. I'll be doing a lot more of this stuff.
